I am trying to set a default value for a date field in my update parameters:
When I try an update with the DefaultValue="<% Now %>", I get this error:
"String was not recognized as a valid DateTime."
The updates work fine if no default value is set and it also works ok if I change the default value to a set string, such as "6/24/06". I've tried using different data sources and datasets, but no luck.
Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having. Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!
i need to retrieve data from a particular field of the gridview according to the selected row to stored it into session .....what i had done so far as following: Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) DetailsView1.PageIndex = GridView1.SelectedIndex Session.Add("receiverName", GridView1.??????) End Sub????? is the part i am not sure what to code.... i tried different method by seems to have problem of convertion.
Hi,I’m new to SQL Express, but I have created a table and a stored proc to populate it.I have dragged the table into a form so I can view the data in a GridView.I have added a button to add new rows to the table. All the above works fine, except when I hit add, the data gets added, but the GridView doesn’t update and show the new data. Is there some code I can add to the add button that also refreshed the GridView? ThanksMike
I have a few Stored procedures that return values, some need parameters passing and others don't. Up to now to access that data in a Web App I have called this procedure using VB after seting up a data block etc. However I notice that the Web Developer express edition has some tools that look like they should help. I have used the in-built tools to create a SQL data source linked to a details view. I then specified that this should connect to my database (sql2005 hosted) and then specified Custom SQL or Stored procedure. From the drop down I can then select the SP that purely returns values. When I try to test this query I get an error to say that the query did not return any data tables. Is there a way to get values returned from a SP in this way? Regards Clive
Hi,I want to add Sql data dependency in GridView. Whenever any changes in database, same will be reflected in Grid. but this should work in both Sql server 2000 and sql server 2005. And when we click on "Pause" button it should stop refreshing.

one of my webpages uses the following sql query to allow the user to search through the database and present the qualifying data in gridview: SELECT * FROM [Table1] WHERE ([comments] LIKE '%' + ? + '%') how could i expand this so that the user can also search through the database but instead by searching through another column such as [type]? thanks in advance
I have a products table in a Sql Server 2005 database. One of the fields contains the products attributes in xml. The most commonly used attribute is color. An element of color is inventory. This is the only way I could think of to maintain inventory numbers of each color of each product using someone else's (opensource) code. An example of an attribute field would be <?xml version="1.0"?> <ArrayOfAttribute xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Attribute> <Name>Color</Name> <Description>Shown in Black</Description> <Selections> <AttributeSelection> <FormattedValue>483 - Black</FormattedValue> <Value>483 - Black</Value> <Inventory>25</Inventory> </AttributeSelection> <AttributeSelection> <FormattedValue>484 - Lt. Tan</FormattedValue> <Value>484 - Lt. Tan</Value> <Inventory>15</Inventory> </AttributeSelection> <AttributeSelection> <FormattedValue>485 - Pink</FormattedValue> <Value>485 - Pink</Value> <Inventory>17</Inventory> </AttributeSelection> </Selections> <SelectionType>SingleSelection</SelectionType> </Attribute> </ArrayOfAttribute> How can I read this into the gridview control so that it makes sense to the user?Diane
I have a webform that I am wanting to display data from a database. Right now I am using the gridview but for future purposes when it comes to maintenance what would be the easiest way to do updates? For example, if I add a new record into the database I would like the webform to automatically update itself to show all the records including the new record I added. Do I need to use a "table" and somehow connect it to a database? Do any stored procedures need to be created? Suggestions/ideas/codes help help help would be verrrry much appreciated!!! Also I am using MS Server 2003 and C# as the programming language. Thank you!!!!
Hello all, I am trying to modify the output of a SELECT statement in a VB asp.net page that pulls data from a SQL DB. I only need to modify one column in the gridview, but I'm having some issues. Here is the situation:SELECT TOP 24 ID, RecID, Timestamp, Answered, Holds, Dropped, Waits, Voicemail, Busied, LiveWaitsFROM mTrafficORDER BY Timestamp DESC The Timestamp column returns a number value (i.e. 564566).In terms of a date, 564566 doesn't mean anything to the user, so I need to convert this number into a recognizable and accurate date. The formula I need to implement is Timestamp/1440 - 1 The following SELECT statement returns the number as a date, but makes all records the same date: SELECT TOP 24 ID, RecID, Convert(datetime, Timestamp/1440 + 1) as Timestamp, Answered, Holds, Dropped, Waits, Voicemail, Busied, LiveWaitsFROM mTrafficORDER BY Timestamp DESC What do I need to do to implement this function dynamically into my gridview? Thanks in advance!
Good Day, Please help me, I have a database that looks like this, Building No. Floor No. Room No. Customer Name Appliances Appliances Codea 1 01 John TV 12a 1 02 //up tob 20 10 james Ref. 22b 20 10 joe Microwave 15 //and soon so if you would notice some rooms are vacant, as it usually happens, the buildings, floors and rooms are fixed except for the customers and the appliances. so at first i made this gridview and display this data in this manner:Customer Location (Building + floor) total rooms Used Rooms Available rooms A1 2 1 1 B2010 2 2 0 so if you would look at the table above, it just SUM up all tenants in a specific Location then Group it by Customer location,but i need to add the appliances in a different format like this: Customer Location (Building + floor) total rooms Used Rooms Available rooms TV Ref Microwave A1 2 1 1 tick B2010 2 2 0 tick tick so this is what i need to show, i already have done the first table (w'o appliances) but how can i make this second table?? please help me, SALAMAT PO.,Thanks
I have a GridView that gets data from an SqlDataSource. It works fine, but now when I want to filter the results and add more parameters to my sql query, nothing happens. My initial select statement in the SqlDataSource contains only 2 parameters, so now when a user clicks a Button, onclick I call a function that is supposed to change the select statement of the SqlDataSource, add 2 more parameters taken from 2 controls, and then update the GridView. This is what I use: dataSource.SelectCommand = "new select command here"; dataSource.SelectParameters.Add("State", txtState.Text); dataSource.SelectParameters.Add("City", txtCity.Text); grid.DataBind(); It compiles, but when I click the button to filter the results, the GridView always looks the same as if nothing happened. I do not know if this is the right way to do it, or am I on the wrong track? Help is appreciated. Thank you in advance.
The function that is supposed to delete a row, is not working. The function is called, and the windows is refreshed, but the row is not deleted.Can anyone see anything wrong with this code:public static void DeleteBlog(int original_BlogID) { string insertCommand = "DELETE FROM Blog WHERE BlogID = @BlogID"; SqlConnection myConnection = new SqlConnection(Blog.ConnectionString); SqlCommand command = new SqlCommand(insertCommand, myConnection); command.Parameters.Add(new SqlParameter("@BlogID", original_BlogID)); myConnection.Open(); command.ExecuteNonQuery(); myConnection.Close();}
Hi, I think the title explains it all really. I cannot configure the SqlDataSource to add Insert, Update and Delete statements - not through the wizard anyway. The view combines two tables, each containing 3 columns. I have tried using different combinations of columns, and ended up selecting all of them (making sure the foreign key column of the first table was given a different alias to the primary key column of the second table) but I still cannot enable editing. Cheers, Patrick
Hello, i currently have a gridview that is populated with data from a SQLServer datasource. I have put an output mask in the select statement, so the date and time attributes are displayed in the format i prefer them to be in. SELECT PatientNo, ConsultantName, HospitalName, CONVERT (varchar, Date, 101), CONVERT (varchar, Time, 8) FROM [Appointment]; However when i click the 'edit' link for a record in the gridview, i am unable to edit the date/time attributes and when i click update to confirm any changes to the other attributes, the values in the date/time attributes are emptied. How can i solve this update problem. I'm guessing i need to configure my SQL UPDATE statement, but bit stuck how i do this. Please help! Thanks, James

Hi all,I have a gridview that bound to a SqlDataSource called SqlDataSourceGridView. I have enabled Edit in my GridView, but I do all the updating in code behind with stored procedure (using onRowUpdating). Now each time when I click "Update", the update went through and all the data got updated, but I received this error: Updating is not supported by data source 'SqlDataSourceGridView' unless UpdateCommand is specified.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NotSupportedException: Updating is not supported by data source 'SqlDataSourceGridView' unless UpdateCommand is specified. What do I need to do to fix this problem?Thanks a lot.

When a new database is created in enterprise manager the path for the database and transaction logs are defaulted to d:mssql7data or wherever you installed SQL Server to initially. Is there a way to change the defaults to place the data on one drive and the logs on a different drive?
Is there a way to change the default data type in SQL Server? If I import a database into SQL Server it makes every non-numeric field a nvarchar field. Is there a way to change this so that these fields would be varchar or char by default? I cannot find any way to redo these as a batch/group update and have to modify every single field manually. Any insights greatly appreciated.
I would like to know how to change the default data directory in SQL Server Express. I have a partitioned hard disk with SQL Installed on the C: drive. I would like to move the data to d: drive. I have just installed SQL and do not have any databases. I have installed SQL with advanced services.
I'm trying to set an int type attribute to 0 for its Default Value, but it keeps reverting to ((0)). What is causing this?
Every int type attribute on that table does the same. There is one bit type attribute and a bunch of other type of attributes, but non of them are giving me a problem. The table is a copy from another database and I did check all the constraints and properties to make sure they're the same.
While running report if user make some selection which reflects no data I want display some default message instead of blank screen. How it can be achieved ?
Hello Everybody, I have a problem that when I insert a date 06.04.2007 on my computer it is interpreted in European style (meaning: dd/MM/yyyy) and the same code on another computer is interpreted in American style (MM/dd/yyyy). So on one computer 06.04 means 6th on April, and on others 4th of June. The question is how can I programatically set that all the SQLDataSources (or en every one of them separately) take the date from the text box in one or the other way – not depending on local settings (it does not matter for me too much which one - just so that it always works the same way. It would be better for me to use European style though).All the best,Joseph
Hi, I've installed SQL 2005 and failed to change the default datalocation during installation. Now I want to change it. Can I do thiswithout having to uninstall and reinstall? And furthermore, is there asystem stored procedure I can use to move existing data and log files(master, msdb, AdventureWorks, etc.)? I seem to remember doing justthis with SQL 2000 some time back.Thanks,Eric
I've created a number of very large databases in Ms Access that I would like to upsize to SQL Server Express. I changed the default data directory location to point to a separate drive with over 400GB of free space on my home pc. However, everytime I try to upsize or link databases using the MS Access Upsizing Wizard the data is saved in the Data directory on my current hard drive and is not saved in the default location I specified. If I create a new database in SQL Express it is saved to the new location. Any ideas on how to force upsizing or uplinked data to go to the new default data location?
Is there a default destination component used when a new data flow is created? The reason I ask is simply curiosity. I have an xml file with 2 pieces of data: item A and item B. A should simply get copied out of the file. B should undergo a quick transform. I set up an XML source such that two columns are mapped correctly to the XML source data of A and B. I set up my data transform task as well. So, if I leave those two components on the .dtsx page with no other components, then will there be a default data flow destination already created? ...OR, do you always have to have a destination component?
I have two instances in SQL on my machine. When creating a New Data Source in BIDS, I can only see the default instance. I have checked the SAC manager to make sure the second instance allows remote connections and the setting are exactly the same as the default. Any ideas? Thanks.
I need to populate some SqlParameter but I temporarily need to populate with a default value for the data type in question. Of course I can work them out, but I was wondering if there is already a way of doing this, from the .Net Classes or from SQL Server but without making a trip to the DB.
